[Elecraft] K2 NB design contest ?

[Gregg R. Lengling]

Actually I had to repair and align his rig before I even attempted to do any 
upgrades (he bought it that way, not in very good shape).  But even for CW 
upgrading the CW waveform and doing the Stability mod and the xtal filter 
upgrades will improve things quite a bit.
